TIRE-INFLA TING APPARATUS.

Specification of Letters Patent.

- Patented June 4, 1912.

Application filed August 24, 1911. Serial No. 645,892.

To all whom it may concern:

Be it known that I, MASON F. STOLBERG, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a Certain new and useful Tire-Inflating Apparatus; and I hereby declare the following to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which, it appertains to make anduse the same, reference being had to the accompanying'drawings, and to the figures of reference marked thereon, which form a part of this specification.

- The object of my invention is the provision of improved, simple and eflicient means which is capable of being easily and quickly attached to or detached from an automobile or other self-propelled vehicle whereby the tires may be inflated by power from the engine of the vehicle through the medium of one of the drive wheels.

The invention is fully described in the following specification, and while, in its.

broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in Which,

Figure 1 is a side elevation of an appa-' ratus embodying my invention partly broken away and in driving engagement with a wheel. Fig. 2 is a plan view of such apparatus. Fig. 3.is an enlarged cross-section of the pump on the'line mo: in Fig. 4, and Fig. 4 is a longitudinal section thereof.

Referring to the drawings, 1 designates a portable base or frame having sides or flanges 2 rising therefrom longitudinally thereof and forming bearings for the shafts or trunnions of a pair of wheel supporting rolls 3 and 4. These rolls are spaced apart longitudinally offhe frame and are peripherally concaved to fit the tread portion of the customary automobile tire, and the roll 3, which is intended to' serve as the drive roll of the pair, is preferablyv of greater d1- ameter than the idler roll 4, as shown.

I base or frame 1. The portion of the-shaft intermediate said bearings is provided with a crank 7, the wrist-pin of which is connected by a pitman 8 to a piston-rod 9, the

piston 10 of which works within a pump cyllnder 11. This pump'cylinder is mounted on the frame 1 at the end of the roll 4, and lSSllOWIl in the present instance as havng each'end provided with a valved air- 1nlet l2 and a valved air-outlet 13 to form a double-acting pump. The air-outlets 13 have communication through a branch pipe 14 with a common flexible tube 15 adapted to lead to any .wheel of an associated automobile for the purpose of inflating the tire of such wheel by an operation of the pump.

The inner-flange 2 is provided along its outer face with a guideway 16 in which the cross head of the pump piston rod 9 slides.

It is evident that to pump up a tire of an automobile it is only necessary to jack up one of the drive wheels thereof to permit the placing of my pumping apparatus thereunder 1n position for such wheel to restupon the rolls 34, as shown .in Fig. 1. Upon a starting of the engine the driving of the wheel in engagement with the pump ing apparatus will effect a driving of the roll 3 and a consequentworking of the pump piston through-the mediumof the crank 7,

pitman 8 and piston-rod 9, thus operating the pump to force air through the tube 1 5 into .the tire to which it is attached.

It is apparent that I have provided a simple and eflicient apparatus for-the pumping up of automobile tires, which apparatus can be packed under a seat of an automobile or in some other convenient place therein, and is capable of being easily and quickly placed in driving engagement'with thedrive wheel of the vehicle or detached therefrom.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations are specified in the claim. 1

Having thus ,described my invention, what I claimas new,;-and.. desire to secure by Letters Patent, is,

, Inan apparatus of the type set forth, a base, a pair of verticalspaced flanges carried by the base and extending longitudinally thereof, one of the flanges being arranged flush with one side of the base and the other flange being spaced from the opposite side of the base, a third short flange I at one end of the base disposed flush with the last named side of the base, said third flange being formed with a bearing interflange of theipair'of flanges to slidingly reeei e the cross-head oft-he-pump. n testimony, whereoflI have hereunto signed my name to this specification in the iresence 'of' twd subscribing witnessesi MASON F. STOLBERG. Witnesses O. W. OWEN, :THQMAS.
